Compile the library `libautoscheduler_anderson2021.so` (Git version: v14.0.0-521-g150a93068) to Halide 16.0.0. Previously, the library did not anticipate the scalar reduction expression, essential for computing the primal and dual norm of the (L-)ADMM algorithm.
Utilize Func::udpate() feature to accumulate the squared sum of each variable in the FuncTuple list. This also simplifies the effort to implement/schedule the GPU routine via `norm.update(i).rfactor(...)`.
